[pianotech] Copper recycling of bass strings

[Ed Sutton]

The trick would be to make something like a string lathe. Clamps in bearings that could hold the string under tension, but spin freely as you pull off the copper.

  When I make universals in the shop, I put the loop in a vice, and then grab the end of the copper at the other end, and start pulling backwards. Of course that's only ro remove a few inches. To do the entire length, she should keep cutting off the loose wire to keep it from spinning. This won't work very well on the thinner strings, about size 10 or higher. On the very thick wire it will be difficult to get an end started

  PS. I've often wondered if this was worth doing to work. With the price of copper as high as it is now, it might not be worth it for us, but it might worth it for a pre-teen.

Hi all,

I have a set of bass strings I removed from an old grand. My 13 year old wants 
to know if she can have the money from recycling the copper.  The recycling 
place won't take it if it's still wrapped on the steel core.

I've tried to find an easy way to have my daughter remove the copper but the 
effortless method has eluded me to date. :-)

Anyone have any ideas?

Thanks,

Rob McCall
